Interesting point about the clutch being a very usful tool, perhaps a torque convertor is not as efficiant but I have found it to be equially usful. I find rocking the car out of a bog easier with an auto, somthing people once told me I would not be able to do. funny the 79 series are manual at the mine sites, but the 250 tonne halpack trucks are autos... ironic.
If your torque convertor overheats, you need an oil cooler or a better technique of driving it. Yeah they use more fuel if you floor them around the city, however you find a more relaxed driving technique normally with an auto and if you look at modern auto fuel economy it is not that much more different to the manual equivilents, not to mention that the modern autos also have higher ratio in the diff allowing them to rev lower when cruising giving you better fuel eceonomy.
Just look at the 100 series V8 Auto, it get's better eceonomy than the DX 4.2 diesel manual when cruising at 100km/h. Food for thought.
Anothe point that has not been brought up is the jutters from corregations causing your foot to "bounce" on the accelerater cuasing damage to your drivetrain in a locked up manual, but not an issue with an auto. With that in mind, there is lesss strain and shock on the whole drive train, motor and passengers with an auto.
